Cam/Crank wheel Q 6.26.0.3; VDF: 6.26.0.18; host: imx2.tcd.ie)

I have a NOS unmarked Cam wheel and a very good second hand crank 
wheel for my engine rebuild. Do I really need to go through the 
procedures in the workshop manual for un marked wheels to set up the 
valve timing or is it safe to just copy the position of the marks on 
the original wheels over to the new ones and use these to establish 
the correct layout.
